Mongoose connection authentication failed - node.js

Question

With this help, I created a super user in the mongo shell: Create Superuser in mongo
user: "try1"
passw: "hello"
In mongo cmd, I have 3 databases: 'admin', 'myDatabase' and 'local'.
Now I try to use this authorized connection to the database called 'myDatabase'.
mongoose.connect('mongodb://try1:hello#localhost:27017/myDatabase');
But this is the error I get:
name: 'MongoError',
message: 'Authentication failed.',
ok: 0,
errmsg: 'Authentication failed.',
code: 18,
codeName: 'AuthenticationFailed' }
Mongoose disconnected
Mongoose disconnected through ${msg}

Answer 1

I had the same problem many hours ago, and after all I solve it. My code is:
mongoose.createConnection(
"mongodb://localhost:27017/dbName",
{
"auth": {
"authSource": "admin"
},
"user": "admin",
"pass": "password"
}
);

Answer 2

Further to #kartGIS, I've added one more option to make the connection code perfect as possible.
mongoose.connect("mongodb://localhost:27017/databaseName", {
"auth": { "authSource": "admin" },
"user": "username",
"pass": "password",
"useMongoClient": true
});

Answer 3

This is the correct answer now. others are not completely correct.
await mongoose.connect("mongodb://localhost:27017/db", {
poolSize: 10,
authSource: "admin",
user: "admin",
pass: "password",
useNewUrlParser: true,
useUnifiedTopology: true,
useCreateIndex: true,
useFindAndModify: false
});

Answer 4

Syntax:
await mongoose.connect('mongodb://username:password#host:port/database?authSource=admin');
Example:
await mongoose.connect('mongodb://myUser:myPassword#localhost:27017/myDataBase?authSource=admin');

Answer 5

Working fine for me on Mongodb 4.2 and Mongoose 5.7.13
Node.js
const Connect = async () => {
let url = "mongodb://localhost:27017/test_db";
try {
let client = await Mongoose.connect( url, {
poolSize: 10,
authSource: "admin",
user: "root",
pass: "root123",
useCreateIndex: true,
useNewUrlParser: true,
useUnifiedTopology: true
} );
log( "Database is connected!" );
} catch ( error ) {
log( error.stack );
process.exit( 1 );
}
}
Connect();

I have the same problem, and it solved by removing the 'authSource' param
/* Not working */
mongoose.connect("mongodb://localhost:27017/test", {
"auth": { "authSource": "admin" },
"user": "admin",
"pass": "admin123",
"useMongoClient": true
});
/* Working */
mongoose.connect("mongodb://localhost:27017/test", {
"user": "admin",
"pass": "admin123",
"useMongoClient": true
});
Tested on Mongoose-v5.0.0.

THIS ANSWER FOR MONGOOSE 6.7.0! USED IN NUXT 3
.env PART
MONGO_URI = "mongodb://localhost:27017/MyBeautifulDB"
MONGO_USERNAME = "mongoadmin"
MONGO_PASSWORD = "mystrongpassword"
DB CONNECTION PART
import mongoose from 'mongoose';
export default async (_nitroApp) => {
const config = useRuntimeConfig();
mongoose.connect(config.MONGO_URI, {
maxPoolSize: 10,
authSource: "admin",
user: config.MONGO_USERNAME,
pass: config.MONGO_PASSWORD
})
.then(() => console.log('Connected to DB'))
.catch((e) => console.log(e));
}
nuxt.config.ts - Register your db connection file to configuration.
export default defineNuxtConfig({
runtimeConfig: {
MONGO_URI: process.env.MONGO_URI,
},
nitro: {
plugins: ['#/server/db/index.ts']
}
})

Answer 8

I got MongoParseError: credentials must be an object with 'username' and 'password' properties when used above answers.
Add username password to auth object solved the issue
try {
await connect("mongodb://localhost:27017/dbname", {
auth: { username: "root", password: "example" },
authSource: "admin",
});
console.log("Connected to mongo db");
} catch (error) {
console.error("Error connecting to mongodb", error);
}
mongodb version 5.0.2
mongoose 6.0.4

Answer 9

Respectively, if your authSource is the database ('myDB' in the example) itself and you are trying to use the ConnectionOption dbName, you have to match authSource.
await mongoose.connect('mongodb://localhost:27017,' {
dbName: 'myDB',
user: 'myUser',
pass: 'asldjaskdj'
);
Will fail with error:
{
"msg": "Authentication failed",
"attr": {
"mechanism": "SCRAM-SHA-1",
"principalName": "myUser",
"authenticationDatabase": "admin",
"client": "...",
"result": "UserNotFound: Could not find user \"myUser\" for db \"admin\""
}
}
Adding authSource: 'myDB' to the connect options will work. Example:
await mongoose.connect('mongodb://localhost:27017,' {
dbName: 'myDB',
authSource: 'myDB',
user: 'myUser',
pass: 'asldjaskdj'
);

Answer 10

I had the same problem. I am using an older MongoDB instance. I simply added authSource=admin to the connection string and it solved the problem.

Answer 11

According to the latest documentation, it should be like this:
mongoose.connect("mongodb://localhost:27017/databaseName", {
"user": "username",
"pass": "password",
"authSource": "databaseName" // users are scoped to DBs
});
Tested on mongoose6.x.x

Answer 12

works for me. i use local database, and mongoose ver 6.9.1
.env file:
DB_HOST=127.0.0.1:27017
DB_NAME=blabla
DB_USER=blablabla
DB_PWD=blablablabla
js file:
const DB = `mongodb://${process.env.DB_HOST}/${process.env.DB_NAME}`;
mongoose
.connect(DB, {
authSource: 'admin',
user: process.env.DB_USER,
pass: process.env.DB_PWD,
})
.then(() => {
console.log('Connected to database.');
})
.catch((err) => {
console.log(err.message);
});

NOTE
This answer is not answering original question but trying to help people in similar situation using NestJS
NestJS
#Module({
imports: [
MongooseModule.forRoot(
'mongodb://mongo:27017/test',
{
auth: {
username: 'root',
password: 'test',
},
authSource: 'admin',
},
),
],
})
export class AppModule {}

Answer 14

I also faced the same issue but resolved it with this
mongoose.connect(mongodb://${dbUser}:${dbPwd}#${dbHost}:${dbPort}/userInfo?authSource=admin). Assuming you have the authentication setup in mongodb.
